in Thoreau’s Journal:

When the leaves fall, the whole earth is a cemetery pleasant to walk in. I love to wander and muse over them in their graves, returning to dust again.

Here are no lying or vain epitaphs. The scent of their decay is pleasant to me. I buy no lot in the cemetery which my townsmen have just consecrated with a poem and an auction, paying so much for a choice. Here is room enough for me.
